Abstract: A central directory system for a network of dial-up communication devices is described. In a preferred embodiment, the communication devices are videoconferencing devices. The system includes a directory management module coupled to the network and configured for importing and exporting directory information to and from a communication device. The directory information received by the management module can be grouped into address books by an access control module coupled to a database in which the address books can be stored. The access control module is further functional to manage access to the address books. Embodiments of the directory system provide systems and methods for providing intelligent dialing service to the dial-up communication device. A dialing algorithm determines a dialing sequence to connect communication devices through a network based on geographic dialing rules and information related to the requesting device.

Abstract: A system and method is disclosed for preparing video conference images. An endpoint has a wide screen display. The disclosed system creates an image with an aspect ratio of about 16:9 for the endpoint. The image is altered or modified to change the aspect ratio to about 4:3. In one example, two portions can be added to the image to increase the overall height of the image. The wide screen display is set to a zoom mode and is capable of substantially displaying the image without the added portions. Alternatively, the image is stretched along its height by a factor of 4/3. The wide screen display is set to the wide mode and is capable of substantially displaying the image without the stretched height. The disclosed system and method can receive signals that the endpoint has a wide screen display and can also inform a user at the endpoint to set the wide screen display to the wide or zoom modes.

Abstract: A system and method for determining if a first and second device are co-located includes first and second sensors for receiving a sample signal. Each sensor is coupled to the first and second devices. The first and second devices each responsively generate a first and second signal representing the sampled signal. Also included is a transmission device located at the first device for transmitting the first signal to the second device and a receiving device located at the second device for receiving the first signal from the first device. Finally, a signal analysis device determines if the first and second devices are co-located.

Abstract: Disclosed herein is a videoconferencing system that has been integrated into a flat panel display or computer monitor. The integration provides an improved form factor for the videoconferencing system. In addition, the integration offers the dual use as a computer monitor and as a videoconferencing system. The system includes a videoconferencing module attaching to a back of the flat panel display. The videoconferencing module has videoconferencing electronics that electronically connect to integral electronics of the display. The system also includes a microphone/camera module attaching to a top of the flat panel display. The microphone/camera module has a camera and microphone that both electronically connect to the videoconferencing electronics.
